IMPROVEMENT IN DISTILLING APPARATUS Sprcification forming part of Letters Patent No. lit},l, dated May 2, 185-4.

To all whom, it may concern.

Be it known that I, HALVOR HALVORSON, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Distilling Apparatus, which may be used for the distillationof oils from rosin or turpentine, as well as for the distillation of various other liquids; and I do hereby de clare that the same is fully described and represented in the following specification, and the accompanying drawing, letters, figures, and references thereof.

The said drawing denotes a longitudinal and vertical section of the said apparatus. In the same, A is a tub in which may be contained any liquid for distillation, such liquid being either nominally fluid (or a solid made so) by the application of proper temperature by any common or practical means. the bottom I affix a pipe, B, having a stopcock, 0, for the escape of the liquid, the volume escaping being regulated by the cock in the usual manner. The volume thus escaping passes out at the lower end of this pipe, which,

by the way, passes down through the capital or into the side of the vessel D, (which vessel I call an ale1nbic,) to very near its bottom, or to that of a cup, E, placed inside this alembic and approaching very near its bottom. To this cup is fastened a shaft, F, whose extreme lower end passes through the cup tight and rests in a step, G, in or on the bottom of the alcmbic. WVhen the distilling apparatus is in use, the shaft F is to be revolved, so as to put the cup E in rotation. The other or upper part of this shaft extends upward through a stuffing-box at H (in the center of the capital a) to any desired elevation above it. Inside the alembic and above the cup E projects toward the shaft from the side of the alembic a rake, I, whose prongs or teeth are made to extend downward with a close proximity of the bottom of the cup, as seen in the drawing. Near the bottom G, and to the outside of the alembic, I fasten a pipe, K, which, at a short distance from the alembic, should be bent or curved upward, as seen at b, a sufiicient distance to admita liquid to stand level in it a little above the orifice of the end of the pipe in the alembic. The discharge-pipe of the capital a is shown at L.

To this tub near In connection with the alembic D another or a train of one or more such alembics may be employed for repeated distillations. Two such alembics are seen at M N, and as provided with rotary cups 0 I, like the cup E, before described. into the still M, and terminates just above the cup 0. The lower end of the pipe K of the vessel D may be constructed so as to separate into several streams any liquid made to flow from it. Each of the stills M N may be provided with a bent discharge-pipe, as seen at K or K such pipe being made like the pipe K, hereinbefore described. Each or one of said stills M N may also be fitted with a rake, I. The capital discharge-pipe R of the still M leads into the still N and terminates over the cup or disk P. That of the still N (seen at S) is used to carry the distillate into a suitable receiver. The arrangement of the several stills so that a liquid can flow from one to the other is shown in the drawing. This being the construction of mydistilling apparatus, its objects now remain to be examined. If in the tub A is contained a liquid composed of two or more other liquids of diiferent specific gravities and volatilities, (such volatilities being known by actual experiment,) and the separation of the said two liquids is desired by the difference of volatility, and if the alembic is heated to the volatilizing-point of temperature of one of the constituent liquids, that constituent will pass off as vapor. During such operation the liquid is to beallowed to flow from the tub A through the pipe B, and into the cup E below its extremity. This cup being, with the alembic D, heated to the volatilizing-point of one of the constituent liquids, such constituent liquid will be vaporized and condensed in thecapital Ct, and will pass off by the discharge-pipe L of the capital, while the other constituent or constituents will remain in the cup E. A quantity of liquid proper might nowbe admitted for distillation. If, during the process of distillation, the liquid constituents not volatile at the temperature of the alembic are not removed from the still, they would be likely to accumulate therein to such an extent as either to soon fill it or seriously interrupt the process of distillation a difficulty to be avoided, if possible. To ob- The pipe K of the vessel D is ledpart of the orifice of this egresspipe, and thus prevent the escape of vapor which it may be desired to have pass off by the capital and its discharge-pipe. The separation of liquids by temperature is not instantaneous.

Having thus described my distilling apparatus, What I claim as of my invention is- The rotary cup E, the rake I, and the discharge-pipe K, (made with a plexure,) or their equivalents, in combination with a still, D, and made to operate therewith, substantially as specified.

In testimony whereof 'I have hereto set my signature this 25th day of May, A. D. 1853. H. HALVORSON. Witnesses:
